Personally, I might have qualified some of those statements with words like: As I understand aikido's potential, ultimately there should be no need to worry about someone taking you to the ground or sucker punching you, etc.

But I suppose is can be both my and Roy's misinterpretation of your expression. But to me (and Roy) it just seemed more like your mis-representation. I'm not trying to pick on you, but rather point out that a new person joining your dojo might come away with the same mis-understanding of your intended message. (FYI: According to NLP, the responsibility for a failed interpretation is typically placed on the sender.)
